Verse 10: And the children of Israel encamped in Gilgal, and kept the passover (Ex. 12:6; Num. 9:5) on the fourteenth day of the month at even in the plains of Jericho.
[And they did the Passover] I expound they did as they sacrificed. For they ate the lamb at the beginning of the following day. It is a Synecdoche of genus (Piscator).
[At evening, בָּעֶרֶב] It is the same time that is elsewhere בֵּין הָעַרְבָּיִם, between the evenings, as it is evident from Exodus 16 and Deuteronomy 16 [concerning which see what things were said at length on Exodus 12, where a great part of what was annotated here by Masius is found]: namely, the last part of the fourteenth day, when the Sun is nearly set. On the Fourteenth Day the lamb was to be slain, but on the night following, that is, which precedes the light of the fifteenth day, it was to be eaten (Masius). Question: What number was this Passover to be reckoned? Response: Some maintain that it is the forty-first, and that the Passover was repeated throughout the entire forty years. For it is not probable that what God commanded to be perpetual was suddenly cast aside (Calvin). Response: The Law of Circumcision was no less perpetual than of Passover, Genesis 17 (Serarius). This does not satisfy others. In the desert Passover was intermitted for thirty-nine years (Serarius, Masius). They present proof: 1. It was not lawful to observe Passover unless circumcised, Exodus 12:48. 2. The Law concerning Passover appears to have regard unto the Promised Land alone; Exodus 12:25, when ye will have come into the land, etc. For what they did at mount Sinai, Numbers 9:2, they did not by Law, but by a new commandment (which would not at all have been necessary, if they were obliged by the Law) and privilege, that they might honor the sanctuary of God (Masius). 3. In the desert there were no sacrifices, Amos 5:25. But the Passover was a sacrifice (Serarius). This was, therefore, the third Passover celebrated by the Israelites: 1. there was one in Egypt; 2. one at mount Sinai; 3. one at this place (Serarius, Lapide, Bonfrerius, Menochius). As the rite of Circumcision was renewed a little previously, so now the ceremony of Passover; so that we might understand that the Israelites holily and religiously entered upon the possession of the Land (Masius). Question: Did the Trans-Jordanian Tribes celebrate this Passover? Response: By no means; for the Passover was able to be celebrated only where the Temple was, Deuteronomy 16:2, 6, 7. Objection: All males were obliged to come three times in a year to their feasts, Deuteronomy 16:16. Response: They were not now bound by that law; either, because they did not yet possess the land of Canaan in peace; or, because they did not know that that ceremony was to be restored so quickly (Bonfrerius).
Passover: This was their third passover: the first was in Egypt, Exodus 12; the second at Mount Sinai, Numbers 9; the third here; for in their wilderness travels these and all other sacrifices were neglected, Amos 5:25.
 Hebrew: וַיַּחֲנ֥וּ בְנֵֽי־יִשְׂרָאֵ֖ל בַּגִּלְגָּ֑ל וַיַּעֲשׂ֣וּ אֶת־הַפֶּ֡סַח בְּאַרְבָּעָה֩ עָשָׂ֙ר י֥וֹם לַחֹ֛דֶשׁ בָּעֶ֖רֶב בְּעַֽרְב֥וֹת יְרִיחֽוֹ׃
 See Exodus 12:6: “And ye shall keep it up until the fourteenth day of the same month: and the whole assembly of the congregation of Israel shall kill it in the evening (בֵּ֥ין הָעַרְבָּֽיִם׃).”
 Exodus 16:12: “I have heard the murmurings of the children of Israel: speak unto them, saying, At even (בֵּ֤ין הָֽעַרְבַּ֙יִם֙) ye shall eat flesh, and in the morning ye shall be filled with bread; and ye shall know that I am the Lord your God.”
 Deuteronomy 16:4, 6: “And there shall be no leavened bread seen with thee in all thy coast seven days; neither shall there any thing of the flesh, which thou sacrificedst the first day at even (בָּעֶרֶב), remain all night until the morning…. But at the place which the Lord thy God shall choose to place his name in, there thou shalt sacrifice the passover at even (בָּעָרֶב), at the going down of the sun, at the season that thou camest forth out of Egypt.”
